Gold is a popular precious metal that has been used for centuries as currency, hedging and jewelry for its noble and beautiful gold color. People love the gold color. But at the same time, the price of gold is high because of its scarcity. Gold coating is a good solution to this problem.
Gold sputtering is a thin film deposition process in which gold or gold alloy is bombarded with high energy ions in a vacuum chamber, causing gold atoms or molecules to be "sputtered" into the vapor and condensed on the substrate to be coated. Sputtering is a method of PVD process, the other two of which are thermal evaporation deposition and electron beam vapor deposition.
These two methods can also be used to coat gold film: in thermal evaporation deposition, the solid gold evaporates in a low-pressure environment with resistive heating elements; and in electron beam vapor deposition, the gold is heated by an electron beam, and then condensed on the substrate to be coated. Since gold coating just deposits a thin film on the subject, it demands a small quantity of pure gold material, so its price is cheaper.
Apart from PVD gold sputtering, there are other ways for gold coatings such as gold plating and gold filling.
Gold plating is a method which deposits a thin layer of gold on the surface of another metal by chemical or electrochemical plating. The advantages of gold plating are inexpensive and easy. However, the film obtained by this method is relatively soft and less durable. What’s worse, its chemical process would cause pollution that is bad for the environment.
Gold Filling is the mechanical bonding of gold to metal under high temperature and pressure. It produces a thicker coating than PVD gold sputtering and gold plating, and thus it is usually more expensive.
The constant contact of skin or clothing may abrade the coatings, especially in watch and jewelry industry. Thus, PVD gold sputtering is preferred in these two industries because the coatings it produces are harder and more durable than that of electrolytic gold plating or gold filling. Compared to other types of gold coatings, the main advantages of PVD gold sputtering coating are their durability, retention of gloss, corrosion resistance and abrasion resistance in contact with the skin, thus extending the life of jewelry. PVD gold sputtering not only provides the exact color and brightness which evokes the general feeling of love and attraction with jewelry, but also has the advantage of being more environmentally friendly and durable than gold plating or gold filling for producing a gold coating.
